     with Section 16(a) of the Securities Exchange Act of 1934 and the

     rules thereunder and Rule 144 of the Securities Act of 1933,

     respectively;



 (2) do and perform any and all acts for and on behalf of the undersigned

     which may be necessary or desirable to complete the execution of any

     such Form 3, 4 and 5 and Form 144 and timely file such form with the

     United States Securities and Exchange Commission and any other

     authority; and



 (3) take any other action of any type whatsoever in connection with the

     foregoing which, in the opinion of such attorney-in-fact, may be of

     benefit to, in the best interest of, or legally required by, the

     undersigned, it being understood that the documents executed by such

     attorney-in-fact on behalf of the undersigned pursuant to this Power

     of Attorney shall be in such form and shall contain such terms and

 The undersigned hereby grants to each attorney-in-fact full power and

authority to do and perform all and every act and thing whatsoever requisite,

delivered to the foregoing attorneys-in-fact.



 IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney

to be executed as of this 13th day of July, 2004.
